Yesterday's mystery #cloud has been ID'd as #cirrocumulus (or perhaps altocumulus) but in any case of the rather rare #undulatus variety, with the waves caused by wind shear at different altitudes: https://cloudappreciationsociety.org/october-2023/ comes somewhat close; see https://cloudappreciationsociety.org/cloud-library/undulatus/ and https://cloudappreciationsociety.org/cloud-library/cirrocumulus/ for details. h/t https://scicomm.xyz/@drlucyrogers@mastodon.social

Just arrived, the result of a rabbit hole I went down recently.
Harich 'Communism without Growth' (1975 Ge, 2034 Sp)
Not available in English ttbomk, but I can read this translation.
Really interesting engagement with the Meadows Limits to Growth report, from the GDR. Parallel to another from Zagreb at the same time.
The quality of the bits I've read is great.
Verso UK should bring it out.
Yvonne Bloor habe ich kürzlich eher zufällig beim Notenstöbern entdeckt: Ihre Musik gefällt mir sehr gut. Studiere gerade "Wedding Song" ein (aus: Heartstrings. Collected Guitar Works, vol. 3). Das Stück gefällt mir sehr gut; hier spielt die Komponistin es selbst, großartige Artikulation und Phrasierung:
UPLOAD-ANYON: Progress Towards an Optimised Twisted Anyon Cavity with High-Sensitivity AM-Noise Detection for an Ultralight Axion Dark Matter Search

Abstract: We propose a superconducting single-mode microwave haloscope based on helical cavity resonators for the detection of ultralight dark matter axions over the mass range $10^{-18}$ to $10^{-13}\,\mathrm{eV}$. Building on the single-mode helical-cavity concept introduced by Bourhill et al. [Phys. Rev. D 108, 052014 (2023); arXiv:2208.01640], we use an inverse-design framework to develop practical resonator geometries compatible with superconducting niobium fabrication. The optimisation employs a figure of merit derived to minimise the measurement time required to achieve a fixed experimental sensitivity. Relative to the heuristic M\"obius-geometry benchmark, the best subtractively manufacturable bulk-niobium design achieves a figure of merit more than three orders of magnitude larger. An experimentally informed microwave interferometric readout model, incorporating measured electronics noise and active suppression of pump amplitude noise, is used to project the sensitivity of the proposed experiment. For an acquisition time of three months, the haloscope is projected to reach $g_{a\gamma\gamma}<10^{-11}\,\mathrm{GeV}^{-1}$ across more than four orders of magnitude in axion mass. The projected sensitivity extends approximately one order of magnitude below the current exclusion limits set by CAST, providing a practical pathway towards a high-sensitivity direct search for ultralight dark matter axions.

Chiefs trading offensive tackle Wanya Morris to Falcons: Sources https://www.nytimes.com/athletic/7352056/2026/06/11/chiefs-wanya-morris-trade-falcons/
I wish #mypy would slow down with adding new features to mypyc, and instead focused on fixing the train wreck that mypyc is right now (since 2023 at least). Like, if your code crashes hard with assertions enabled, then it's broken, period. Ignoring proper testing and shoving the issue under the carpet doesn't make it right.

Designed-Source Reductions and a Dual-Purpose Feasibility Band for Semantic Rate-Distortion

Abstract: The joint rate-distortion framework of Stavrou and Kountouris (IEEE Transactions on Communications 2023) characterises dual-fidelity tradeoffs for semantic communication on stochastic semantic sources. Many task-oriented communication systems instead use designed sources, where the semantic object is a deterministic oracle allocation $\phi^(t)$ rather than a stochastic quantity given by nature. We isolate the subclass of designed sources under smooth concave utility with assumptions A1, A2 and Euclidean allocation codomain, and restrict the encoder class to deterministic common-category mappings. Within this subclass the SK exponential-tilting decoder and generalised Blahut--Arimoto iteration specialise to conditional-mean decoding and Lloyd--Max stationarity on $\phi^(t)$. When the second fidelity is a monotone single-letter distortion, the joint problem stays inside the SK admissible class; the common-category SK rate is lower-bounded by the max of the corresponding Shannon rate-distortion functions, with equality only when the common-category reconstruction is compatible and RDF-optimal. When the second fidelity is aggregate verification, the joint problem leaves the SK single-letter class and admits a constrained-design feasibility band $R_{\min}(\varepsilon^) \leq R \leq R_{\max}(\beta^)$ of width $\log_2(K_{\max}/K_{\min})$ bits in partition cardinality. The reduction and the band are scope statements on the SK apparatus, not modifications to it. A smart-grid economic-dispatch example with a non-technical-loss-detection contrast illustrates the band.
